I have fed species greater than you, and I have starved species greater. My oceans, my soil, my flowing streams, my forests. They all can take you or leave you. how you choose to live each day, whether you regard or disregard me doesn't really matter to me one way or the other. Your actions will determine your fate, not mine. I am nature. I will go on. I am prepared to evolve. Are . you?
